Subject: [EXT] [PATCH v2 16/16] ARM: dts: ls1021a-tsn: use generic
"jedec,spi-nor" compatible for flash

Caution: EXT Email

We cannot list all the possible chips used in different board revisions, just
use the generic "jedec,spi-nor" compatible instead.  This also fixes
dtbs_check error:
['s25fl256s1', 's25fl512s', 'jedec,spi-nor'] is too long
